EVERLASTICK VARNISH, INC., OF GHATTANOOGA, TENNESSEE, A CORPORATION OF TENNESSEE ROLL FOR SPINNING MACHINES AND METHOD AND COMPOSITION FOR- PRODUCING THE SAME Application filed November 7, 1930. Serial No. 494,125.

"according to the present practice, the worn rolls must be returned to the factory to be provided with new coverings.

' Objects of the present invention are to provide an improved drafting roll, to provide an improved covering for such rolls that will be of an efficient nature and capable of resisting wear to a high degree, to provide an improved composition to be applied to the roll covering that will preserve and protect the same against wear, and .to provide a method whereby the roughened surfaces of worn roll coverings can be readily restored or reconditioned for further use. i

The invention with other objects and advantages thereof will be understood from the hereinafter contained detailed description when considered in connection with the accompanying drawings forming part hereof and illustrating drafting rolls constructed in accordance with the teachings of the invention.

In the drawings:

Figure 1 is an elevation of a roll constructed in accordance with the present invention; Figure 2 is a transverse section; I

Figure 3 is an elevation of a drafting roll with the leather covering worn and roughened on its outer surface.

Figure 4 is a transverse section of the roll illustrated in Figure 3.

Figure 5 is a transverse section of a roll with a worn leather covering after the covering has been treated to recondition the same.

In Figures 1 and 2 of the drawings is illustrated a roll comprising a core 1, a fiber filling 2, and an outer covering 3 of sheepskin, the construction so far described being a conventional form of drafting roll.

In accordance with the present invention, a composition coating is applied to the outer face of the leather covering 3. The composition is applied to the roll in the form of a solution consisting of a mixture of ribbon glue, acetic acid, oil of origanum, wood alco hol, powdered soapstone andwater. The following is an example of the proportions in which the different ingredients are employed in the composition. To prepare one gallon of the solution, take threepounds of ribbon glue and thoroughly beat up and dissolve the same with one half gallon of acetic acid No. 8. Then add two ounces of oil of origanuin, one pint of wood alcohol, two full tablespoons of powdered soapstone and one pint of water. Instead of using ribbon glue as a filler and binder, other proteins having like qualities may be employed, and in place of oil or origanum, which acts as a drier and preservative, other oils having like properties may be used.

The wood alcohol acts as a filler and dry ing agent. The powdered soapstone acts as a filler and is effective in producing a slick protective wearing surface on the roll so that the yarn and yarn ends will not stick thereto.

The solution is applied by rubbing the same over the surface of the roll and particularly. satisfactory results have been obtained by employing rubber gloves and dipping the gloved hand into the solution and rubbing over the surface of the roll. After application of the solution, the roll is placed in a rack to dry, and, after'from one to three hours, is ready for use. i

A leather covered roll provided withthe composition coating as hereinbefore set forth will resist wear much better than the ordi-. nary construction of roll equipped with a plain leather covering, and has proven highlysatisfactory in use. The resulting roll surface will not become wet or sticky and the yarn will not adhere to it.

The invention also comprehencls the treatment of rolls havin old worn coverings, which would ordinarily be discarded, to restore or recondition the same for further use. In Figures 3 and 4 of the drawings, I have t, shown an old or worn roll, and in Figure 5 is illustrated the old roll after the same has been reconditioned. In accordancewith the teachings of the invention, a coating of the composition lhereinbefore 1 described is appliedi-fio. the .WQIin nong'hene'd ifacei of theused roll and the same is allowed to dry from fifteen to twenty minutes. Next the roll is smoothedoif as by the use of an emery cloth and a second-coating of the-solutionapplied.

The roll is then allowed to dry and is ready for use in from one to three hours.

The improved roll produced in accordance with the present invention possesses important advantages. better and remain serviceable for a much longer period than the; ordinary construction ofroll provided with a plain leather covering. As will be appreciated, 23,11 important featureofithe invention resides in the method of reconditioning Worn rolls, the S&II165:PIO-

vidin-g for (readily reconditioning the worn roughened coverings, which in present practice-arediscarded. V The rolls maybe reconditioned a .numberof times and the invention thuseprovidesior a considerable reduction in the expenseincident to'the use ofdra-fting rolls. v What I claim is 1. A drafting :roll for spinning. machines,
